JohnConnor writes: William Shatner and real life Canadian astronaut Chris Hadfield have been having a conversation via twitter while one of them was in space (I'm not saying which one, as I don't want to spoil the surprise). It seems that Captain Kirk is impressed by real space work. Or it could be that he is impressed by Hadfield, who is quite a remarkable guy... Of course the Canadian Space Agency couldn't pass up this opportunity for excellent PR and invited Shatner to visit its headquarters and talk live with the astronaut.
